Check a land parcel, company and generating unit, before making your first expenditure
Three entry points using the same public registers: a land parcel profile with available capacity and the queue at the nearest substation, the local spatial development plan, nature and flooding; a company profile with licences, MIOZE entries, KRS data and VAT status; and a unit profile with the capacity obligation and agreement duration from a capacity market auction. A source is shown beside every value and the dataset date beside every dataset.
available capacity: 12.4 MW · queue: 18 applications / 214 MWillustrative values · Full access: listed substation, distance, capacity and total queue in MW
The wrong site and the wrong counterparty cost more than the entire initial assessment
This is the advance payment alone for connection to a grid above 1 kV (PLN 60/kW, based on the statutory rate). Before paying it, check the reported capacity and substation queue according to the operator’s latest data. The Platform does not replace connection conditions: the operator makes the binding determination.*
This is the number of entries in operators’ queue lists: issued connection conditions, executed agreements and, for one operator, also sources that are already connected (the publication date for each operator is shown in the tool). Buying land without checking the queue means joining the end of a queue that is not visible on the map.
This is how many registers you check separately for one land parcel: land and buildings register, local spatial development plan, GDOŚ, flooding, capacity list, queue, KRS and VAT taxpayer list.
Three entry points using the same registers
Location, company, generating unit. Each entry point uses public registers, shows the named source beside each value and the dataset date beside each dataset. The views below use illustrative data. You can also find the complete breakdown of what is free and what Full access includes in the tutorial →
Check a land parcel for RES
Listing map and any land parcel check in one view.
Open a map of Poland with renewable energy projects and land. Markers show capacity, the adjacent list shows what is currently on screen, and filters narrow the results by technology, stage and capacity range. Click anywhere on the map or enter an address to open a profile for that land parcel.
- Land parcel profile: available capacity at the nearest substation, application queue, local spatial development plan, nature protection designations and flood hazard.
- The land parcel boundary is drawn on the same map, so you can see the project’s surroundings.
- Every value has a named source, and every dataset has a dataset date.

Check a company and its installations
Before signing an agreement, check whether the counterparty has what it claims to have.
3,309 licences of the President of URE and 8,571 installations in the register of generators, counted by register row, in a single search instead of two separate registers on the authority’s pages. You enter a name, a NIP number or a locality and see at once whether the company you are negotiating a lease, an electricity sale agreement or a project purchase with appears where it claims to appear.
- Every company by tax identification number (NIP), with KRS registration data on its profile.
- Status in the Ministry of Finance VAT taxpayer list, with the check date.
- The register search tool is open to everyone, with no query limit.

Check generating units and the capacity market
Before signing an agreement with a capacity provider, check what it committed to in the auction.
Capacity market units from the latest main auction, each with its code, type, capacity obligation amount and agreement duration, together with the provider to which it belongs. Using the same entity’s tax identification number (NIP), we add its licences issued by the President of the Energy Regulatory Office (URE) and MIOZE register entries, so one entry point shows both the capacity obligation and the authorisations.
- Search by unit code, provider or tax identification number (NIP).
- Filters: unit type and annual or multi-year agreement.
- Unit profile: latest delivery year and earlier auctions for the same code.
- Provider profile with the total capacity obligation in the latest delivery year.

The same registers nationwide rather than for a single location, company or unit. All four are free of charge, with no search limits.
Available grid connection capacity in Poland
Lists from five distribution system operators (PGE, Tauron, Enea, Energa and Stoen) and the transmission system operator PSE on one map: nearly 600 primary substations (GPZ) with capacity reported for generators, the number of applications in the queue and their total megawatts. Instead of opening six lists in six formats, filter one map by voivodeship, voltage and capacity threshold. Each operator’s data includes its publication date, so you know the date of the information you are viewing. A browsable table of substations is shown beside the map.
Open the available-capacity map →RES generation curtailment
Hourly PSE data for the whole country and pressure at around 30 extra-high-voltage nodes: redispatch hours, hours with negative prices, and sequences of six or more consecutive such hours that the Renewable Energy Sources Act excludes from support (certificates of origin, Article 46). This covers the national scale and transmission nodes, not an individual land parcel.
Check the scale of constraints →RES building permits (GUNB)
More than 24,000 renewable energy installation building permit cases since 2016 from the GUNB application register: breakdown by solar PV, wind, energy storage and biogas, by voivodeship and municipality, plus procedure duration calculated from actual case dates rather than authorities’ declarations. The dataset is refreshed on business days and includes a dataset date.
See what receives permits →Calculate grid connection charges
Free fee calculator based on statutory rates (Article 7 of the Energy Law as in force from 30 April 2026): application fee, advance payment, security and deadlines, including 14 days to provide security after executing a connection agreement. Scope: connections to a grid above 1 kV; the operator issues the binding conditions. The scope is intentionally narrow: the calculator calculates rates from the supplied parameters because the form does not identify a substation. A connection report with the reported capacity, queue and deadlines for a specific substation opens from a land parcel check, where the point has already been matched. The calculator itself and the lists themselves remain free of charge.
Calculate the advance payment and security →Today these are eight separate search tools. Check a land parcel for renewable energy combines them into one result.
Your current path and the same land parcel with Full access: values beside the fields, with a named source for each one. Switch to the company profile and unit profile because the subscription covers all three, for as many specific checks as you need. Enter your land parcel number below to see which layers we have for it. Your first check requires no account; subsequent checks require a free account.
Independently, layer by layer (free of charge)
Each source has its own search tool, format and publication date. You assemble the result yourself in your notes. We keep this route free of charge; the entry points and reports above make it more convenient.
The same public registers. Eight entry points and manual assembly of results, or one search with a complete set of layers beside the fields.

Where this data comes from
URE, PSE, DSO, GUNB, GUGiK, GDOŚ, KRS and the Ministry of Finance VAT taxpayer list. Every value has a named source. No forums, listings or guesswork.
Each dataset includes the publication date of its source list. You know what information you are relying on before deciding about land or a counterparty.
The demonstrations on this page contain illustrative values and state this expressly. With Full access, every figure is labelled with its actual source list.
We show VAT status with the check date. We refresh GUNB permit data on business days. We show capacity lists with the operator’s publication date: when updates are slower, the source publishes more slowly, not us.
Six situations, one subscription
Before buying land: a land parcel profile with available capacity, the queue and environmental information, for as many sites as you analyse.
Before signing a lease: what the grid and plan say about the checked point on your land parcel, and whether the lessee is who it claims to be. You can check one land parcel before signing a lease in the first month for PLN 19 excluding VAT; cancel the subscription before renewal.
Before paying for a project: the connection agreement clock, substation status and the seller’s profile by tax identification number (NIP).
Before entering into an agreement: the seller’s licences, corporate body composition and year-on-year financial result.
Before you list a project: organise the documents according to the data room checklist and add a listing without prices on the offer map.
Before you choose a substation: capacity for consumption where the operator publishes it, storage projects in the application queue, and national facts on negative prices and redispatch.

Aleksandra Lindner, advocate · HWW partner, energy and renewable energy lawOne advance payment made in the wrong location is PLN 60,000 for 1 MW (advance payment of PLN 60/kW based on the statutory rate). Full access costs PLN 19 excluding VAT (PLN 23.37 including VAT) per month for the first 3 months.
Then PLN 199 excluding VAT/month (PLN 244.77 including VAT). That is still less than half of one percent of a single advance payment for 1 MW. The price includes unlimited checks of land parcel, connection point and company profiles, plus your project and land listings with no limit on the number of listings. Renews automatically; cancel at any time. Fixed price, with no negotiation.
Included in the price from day one:
- land parcel and land profiles with unlimited checks
- connection point profiles with agreement deadlines
- company profiles: KRS, corporate body composition and shareholders to the extent disclosed in the dataset, VAT status with the check date
- generating unit and capacity market profiles: capacity obligation, agreement duration, provider from the Energy Regulatory Office (URE) list

Currently in the tools: 590 substations with reported capacity for generation (operator lists, with each operator’s publication date shown in the tool) · 24 779 renewable energy building permit cases (GUNB, as at 17.09.2026) · 3,308 URE licences (the URE Registry tool provides the retrieval date) · 6,500 company profiles (KRS, as at 10.07.2026)
Start at PLN 19 excluding VAT/month → Compare both options: with and without third-party listing unlocks →Will PLN 19 give me access to sellers’ contact details in listings?
No. This option provides the tools and your own listings. Unlocking a third-party listing (land parcel numbers and seller contact details) carries a separate charge: PLN 49 excluding VAT up to 25 MW, PLN 389 excluding VAT above that threshold, or a subscription option for PLN 490 excluding VAT/month with unlimited listing unlocks. Unlimited means as many listing unlocks as you need for your work.
Where does the data come from and is it current?
From public registers: URE, PSE, operator lists, GUNB, GDOŚ, KRS and the VAT taxpayer list. Values in the tools have named sources, and the list publication date is shown beside the data in the tool and in the “Dataset status” line at the bottom of this page.
Can I cancel after the first month?
Yes. The subscription renews monthly and you can cancel at any time without a notice period. You can subscribe for a month, check your land parcel and cancel; this is normal use of Full access.
What happens after the third month?
From the fourth month, the subscription renews automatically at PLN 199 excluding VAT/month (PLN 244.77 including VAT), with no change of scope: the tools and the listings with no limit on their number both remain. Your next renewal date is shown on the Payments page in your account, where you can also cancel the subscription; access continues until the end of the paid period.
